Edit DNA LODs

Drops a DNA down to a subset of its own LODs, appends new LODs cloned from an existing one, or both in the same pass.

When to use it

Drops a DNA down to a subset of its own LODs, appends new LODs cloned from an existing one, or both in the same pass.

How to use it

  1. 1

    Wire a DNA in

  2. 2

    Keep LODs: list the LODs to keep, ascending, e.g. [0, 2] to keep only LOD 0 and LOD 2 (renumbered 0 and 1). Leave empty to keep every LOD

  3. 3

    Add Cloned LODs: how many new LODs to append, each a byte-identical copy of Clone From LOD - "immediately valid, evaluates identically". Clone From LOD indexes the mesh after the keep-filter above, so -1 (the default) always means "the last LOD that survived the filter"

  4. 4

    Press Apply LODs

    A dropped LOD's own meshes, blendshape targets and LOD-only behavior rows are gone - re-adding it later starts from whatever the DNA looks like then, not from what was dropped.

Pins

Pin Type Description
DNA DNA The DNA to edit the LODs of.
Pin Type Description
DNA DNA The DNA with its LODs edited. Empty until Apply LODs succeeds - never a partial file.

Settings

Setting Type Description
Keep LODs List of Whole number LODs to keep, ascending, no duplicates. Empty (the default) keeps every LOD - Apply LODs then only appends clones, if any. Writable by the in-app agent but hidden from the ordinary properties rows.
Add Cloned LODs Whole number How many new LODs to append, each a clone of Clone From LOD. 0 skips the additive half entirely.
Clone From LOD Whole number Which LOD the appended clones copy, indexed after Keep LODs has already run. -1 means the last LOD that survived the keep-filter.
